DOCUMENT COMPARISON METHOD AND DOCUMENT COMPARISON SYSTEM BASED ON VARIOUS INTER-DOCUMENT SIMILARITY CALCULATION METHOD USING ADAPTIVE WEIGHTING

摘要

One embodiment provides a system for comparing documents based on different document-similarity calculation methods using adaptive weighting. During operation, the system receives (202) at least two document-similarity values associated with two documents, wherein the document-similarity values are calculated by different document-similarity calculation methods. The system then determines (204) the weight of a respective document-similarity calculation method for each of the two documents, as well as a weight-combination function (206) for calculating a combined weight of the respective document-similarity calculation method associated with the two documents. Next, the system generates (208) a combined similarity value based on the document-similarity values and the weight-combination function.
